NEW HAVEN -- Family and friends are grieving the loss of a 13-year-old boy who was shot to death while hanging out with friends in New Haven Sunday night, and one of those friends has been charged with his murder.

Police said Marquell Banks, a seventh-grader at Fair Haven School, was shot by 18-year-old Science Burress around 7:30 p.m. Sunday at a house on Porter Street. Burress fled from the scene, but turned himself in Monday morning after a warrant was issued charging him with murder, reckless endangerment, possession of a sawed-off shotgun and unlawful discharge of a weapon.

Burress appeared in court in New Haven on Tuesday. The judge ordered his bond left at $2 million and sealed the court files.

His father told the press gathered outside the courthouse that the shooting was an accident. He said his son was a good student, and had just graduated from high school.

Banks' family didn't comment after the court appearance.

Two of Banks' other friends, 17-year-old Mike Newsome and 18-year-old Chris Standberry, were both in the house also, and are still trying to come to reality with what happened.

"I've never seen anything like this in my life before," said 17-year-old friend Mike Newsome, "I've never had anyone die in my arms, it's hard."

Newsome and Standberry say the four were hanging out inside the Porter Street home when Burress accidentally fired his gun, a sawed-off shotgun.

"He was like `yo I shot little bro by accident, I shot little bro by accident,'" said 18-year-old Chris Standberry. "I looked at the TV, and I see brains on the TV and him right here looking at me and I just got down and started helping him. I didn't know what else to do."

Banks' two friends who were there when he was shot, were visibly grieving and in pain as police cleaned up the crime scene Monday.

"Little Quelly looked up to me and Chris," said Newsome. "He always wanted to be around us all and he just wanted to chill with us that day so I feel like if I were to have told him to just go somewhere else instead of hanging with us this wouldn't have happened."

Neither can believe Burress would do something like this.

"After this happened he texted me and said `call me I'm about to go to the police station' and then he said `how am I going to live with this,'" said Standberry, "So I know he cared for this little man."

As for Banks' family, they're grieving over a life cut too short.

"He was just a fun-loving kid, always interested in sports, was never into the streets, good student," said his sister, Laquita Wallace, "So he didn't deserve this, no child deserves this."

Burress is being held on $2,000,000 bond.

A vigil waws held Monday night outside of Banks' home in Fair Haven.

School counselors have been made available to the students and staff at Fair Haven School.
